In various locations, these weapons account for most of the firearms used in crime in others, their production is institutionalized, providing essential income for local gunsmiths. Improvised and craft-produced firearms remain an important source of firepower for a wide range of actors, including tribal groups, poachers, criminals, insurgent groups, and even some states and quasi-state groups. Although the number of craft-produced small arms and light weapons is difficult to estimate, they are prevalent and range broadly in sophistication and quality.
